Ngeli xesha lokunyathela kwetekhnoloji eyothusayo, iinkqubo zokukhangela zavela njengeentsika ezisisiseko, eziqhubela phambili ukuqhubela phambili, ngakumbi kumacandelo abaluleke kakhulu. Uhambo olusuka kuhambo lwasezulwini olusisiseko ukuya kwiiNkqubo zokuNavigation ze-Inertial eziphucukileyo (INS) zibonakalisa iinzame zoluntu ezingayekeleliyo zokuhlola kunye nokukhomba ukuchaneka. Olu hlahlelo lujonge nzulu kubuchwephesha obuntsonkothileyo be-INS, iphonononga itekhnoloji ye-Fiber Optic Gyroscopes (iiFOGs) kunye nendima ebalulekileyo yePolarization ekuGcineni iFiber Loops.
Icandelo 1: Ukucacisa iiNkqubo zokuHamba ngokuNgaphakathi (INS):
I-Inertial Navigation Systems (INS) ivelele njengezixhobo zokuncedisa ukuhamba ngokuzimeleyo, ngokuchanekileyo ukubala indawo yesithuthi, ukuqhelaniswa, kunye nesantya, esizimeleyo kwiimpawu zangaphandle. Ezi nkqubo zingqinelanisa intshukumo kunye nezinzwa ezijikelezayo, zidibanisa ngaphandle komthungo kunye neemodeli zokubala zesantya sokuqala, indawo, kunye nokuqhelaniswa.
I-Archetypal INS ibandakanya izinto ezintathu eziphambili:
I-Accelerometers: Ezi zinto zibalulekileyo zibhalisa isantya somda wesithuthi, ukuguqulela intshukumo kwidatha enokumetwa.
· IiGyroscopes: Okudityanisiweyo ekumiseleni isantya se-angular, la malungu abaluleke kakhulu ekuqhelaniseni inkqubo.
· Imodyuli yeKhompyutha: Iziko le-nerve ye-INS, ukusetyenzwa kwedatha eninzi ukuvelisa uhlalutyo lwexesha langempela.
Ukungakhuseleki kwe-INS kwiziphazamiso zangaphandle kwenza ukuba ibaluleke kakhulu kumacandelo okhuselo. Nangona kunjalo, iyasokola 'nokukhukuliseka' - ukubola okuchanekileyo ngokuthe ngcembe, kufuna izisombululo ezintsonkothileyo ezinje ngokudityaniswa koluvo lokunciphisa iimpazamo (Chatfield, 1997).
Icandelo 2. IiNdyebo zokuSebenza zeFiber Optic Gyroscope:
Ii-Fiber Optic Gyroscopes (FOGs) zibhengeza ixesha loguqulo kwimvamvo ejikelezayo, ukuphazamisa ukukhanya. Ngokuchaneka kumbindi wayo, iiFOG zibalulekile ekuzinziseni nasekuqhubeni inqwelo moya.
I-FOGs isebenza kwisiphumo se-Sagnac, apho ukukhanya, ukunqumla kwi-counter directions ngaphakathi kwe-coil ye-fiber ejikelezayo, kubonakalisa ukutshintshwa kwesigaba esihambelana notshintsho lwezinga lokujikeleza. Le ndlela yokwenza i-nuanced iguqulela kwi-angular velocity metrics ezichanekileyo.
Amacandelo abalulekileyo aquka:
· Umthombo wokukhanya: Indawo yokuqala, ngokuqhelekileyo ilaser, eqalisa uhambo oluhambelanayo lokukhanya.
· Ikhoyili yeFayibha: I-conduit ye-optical ejiyileyo, yandisa i-trajectory yokukhanya, ngaloo ndlela ikhulisa umphumo we-Sagnac.
· I-Photodetector: Eli candelo libona iipateni ezintsonkothileyo zokuphazamiseka kokukhanya.
Icandelo 3: Ukubaluleka kwePolarization Ukugcina iiLophu zeFayibha:
Ukugcinwa kwePolarization (PM) Ii-Fiber Loops, i-quintessential ye-FOGs, iqinisekisa imo ye-polarization efanayo yokukhanya, isigxininiso esibalulekileyo ekuchanekeni kwepateni yokuphazamiseka. Ezi ntsinga zikhethekileyo, ukulwa ne-polarization mode dispersion, bolster FOG sensitivity kunye nokunyaniseka kwedatha (Kersey, 1996).
Ukukhethwa kweefiber ze-PM, ezichazwe ziimeko ezingxamisekileyo zokusebenza, iimpawu zomzimba, kunye nokuvisisana kwenkqubo, kuphembelela iimethrikhi zokusebenza ezigqwesileyo.
Isigaba 4: Izicelo kunye nobungqina bobuGcisa:
IiFOG kunye ne-INS zifumana iresonance kuzo zonke iinkqubo ezahlukeneyo, ukusuka ekulungiseleleni iiforoyi zasemoyeni ezingaqhutywa mntu ukuya ekuqinisekiseni uzinzo lwe-cinematic phakathi kokungaqiniseki kwendalo. Ubungqina bokuthembeka kwabo kukusasazwa kwabo kwi-Mars Rovers yeNASA, iququzelela ukusingathwa kolwandle ngaphandle kokhuseleko olukhuselekileyo (Maimone, Cheng, and Matthies, 2007).
Iindlela zentengiso ziqikelela i-niche ekhulayo yezi teknoloji, ezineevekhtha zophando ezijolise ekomelezeni ukomelela kwenkqubo, iimatriki ezichanekileyo, kunye nembonakalo yokuguquguquka (MarketsandMarkets, 2020).
